Role of a novel photosystem II-associated carbonic anhydrase in photosynthetic carbon assimilation in Chlamydomonas reinhardtii. (1/1304)

Intracellular carbonic anhydrases (CA) in aquatic photosynthetic organisms are involved in the CO2-concentrating mechanism (CCM), which helps to overcome CO2 limitation in the environment. In the green alga Chlamydomonas reinhardtii, this CCM is initiated and maintained by the pH gradient created across the chloroplast thylakoid membranes by photosystem (PS) II-mediated electron transport. We show here that photosynthesis is stimulated by a novel, intracellular alpha-CA bound to the chloroplast thylakoids. It is associated with PSII on the lumenal side of the thylakoid membranes. We demonstrate that PSII in association with this lumenal CA operates to provide an ample flux of CO2 for carboxylation.  (+info)

Characterization of Chlamydomonas reinhardtii zygote-specific cDNAs that encode novel proteins containing ankyrin repeats and WW domains. (2/1304)

Genes that are expressed only in the young zygote are considered to be of great importance in the development of an isogamous green alga, Chlamydomonas reinhardtii. Clones representing the Zys3 gene were isolated from a cDNA library prepared using zygotes at 10 min after fertilization. Sequencing of Zys3 cDNA clones resulted in the isolation of two related molecular species. One of them encoded a protein that contained two kinds of protein-to-protein interaction motifs known as ankyrin repeats and WW domains. The other clone lacked the ankyrin repeats but was otherwise identical. These mRNA species began to accumulate simultaneously in cells beginning 10 min after fertilization, and reached maximum levels at about 4 h, after which time levels decreased markedly. Genomic DNA gel-blot analysis indicated that Zys3 was a single-copy gene. The Zys3 proteins exhibited parallel expression to the Zys3 mRNAs at first, appearing 2 h after mating, and reached maximum levels at more than 6 h, but persisted to at least 1 d. Immunocytochemical analysis revealed their localization in the endoplasmic reticulum, which suggests a role in the morphological changes of the endoplasmic reticulum or in the synthesis and transport of proteins to the Golgi apparatus or related vesicles.  (+info)

Photosystem I is indispensable for photoautotrophic growth, CO2 fixation, and H2 photoproduction in Chlamydomonas reinhardtii. (3/1304)

Certain Chlamydomonas reinhardtii mutants deficient in photosystem I due to defects in psaA mRNA maturation have been reported to be capable of CO2 fixation, H2 photoevolution, and photoautotrophic growth (Greenbaum, E., Lee, J. W., Tevault, C. V., Blankinship, S. L. , and Mets, L. J. (1995) Nature 376, 438-441 and Lee, J. W., Tevault, C. V., Owens, T. G.; Greenbaum, E. (1996) Science 273, 364-367). We have generated deletions of photosystem I core subunits in both wild type and these mutant strains and have analyzed their abilities to grow photoautotrophically, to fix CO2, and to photoevolve O2 or H2 (using mass spectrometry) as well as their photosystem I content (using immunological and spectroscopic analyses). We find no instance of a strain that can perform photosynthesis in the absence of photosystem I. The F8 strain harbored a small amount of photosystem I, and it could fix CO2 and grow slowly, but it lost these abilities after deletion of either psaA or psaC; these activities could be restored to the F8-psaADelta mutant by reintroduction of psaA. We observed limited O2 photoevolution in mutants lacking photosystem I; use of 18O2 indicated that this O2 evolution is coupled to O2 uptake (i.e. respiration) rather than CO2 fixation or H2 evolution. We conclude that the reported instances of CO2 fixation, H2 photoevolution, and photoautotrophic growth of photosystem I-deficient mutants result from the presence of unrecognized photosystem I.  (+info)

Induction of coproporphyrinogen oxidase in Chlamydomonas chloroplasts occurs via transcriptional regulation of Cpx1 mediated by copper response elements and increased translation from a copper deficiency-specific form of the transcript. (4/1304)

Coproporphyrinogen III oxidase, encoded by a single nuclear gene in Chlamydomonas reinhardtii, produces three distinct transcripts. One of these transcripts is greatly induced in copper-deficient cells by transcriptional activation, whereas the other forms are copper-insensitive. The induced form of the transcript was expressed coordinately with the cytochrome c6-encoding (Cyc6) gene, which is known to be transcriptionally regulated in copper-deficient cells. The sequence GTAC, which forms the core of a copper response element associated with the Cyc6 gene, is also essential for induction of the Cpx1 gene, suggesting that both are targets of the same signal transduction pathway. The constitutive and induced Cpx1 transcripts have the same half-lives in vivo, and all encode the same polypeptide with a chloroplast-targeting transit sequence, but the shortest one representing the induced form is a 2-4-fold better template for translation than are either of the constitutive forms. The enzyme remains localized to a soluble compartment in the chloroplast even in induced cells, and its abundance is not affected when the tetrapyrrole pathway is manipulated either genetically or by gabaculine treatment.  (+info)

Group II intron splicing in Escherichia coli: phenotypes of cis-acting mutations resemble splicing defects observed in organelle RNA processing. (5/1304)

The mitochondrial group IIB intron rI1, from the green algae Scenedesmus obliquus ' LSUrRNA gene, has been introduced into the lacZ gene encoding beta-galacto-sidase. After DNA-mediated transformation of the recombinant lacZ gene into Escherichia coli, we observed correct splicing of the chimeric precursor RNA in vivo. In contrast to autocatalytic in vitro self-splicing, intron processing in vivo is independent of the growth temperature, suggesting that in E.coli, trans -acting factors are involved in group II intron splicing. Such a system would seem suitable as a model for analyzing intron processing in a prokaryotic host. In order to study further the effect of cis -mutations on intron splicing, different rI1 mutants were analyzed (with respect to their splicing activity) in E.coli. Although the phenotypes of these E. coli intron splicing mutants were identical to those which can be observed during organellar splicing of rI1, they are different to those observed in in vitro self-splicing experiments. Therefore, in both organelles and prokaryotes, it is likely that either similar splicing factors or trans -acting factors exhibiting similar functions are involved in splicing. We speculate that ubiquitous trans -acting factors, via recent horizontal transfer, have contributed to the spread of group II introns.  (+info)

Group II intron splicing in chloroplasts: identificationof mutations determining intron stability and fate of exon RNA. (6/1304)

In order to investigate in vivo splicing of group II introns in chloroplasts, we previously have integrated the mitochondrial intron rI1 from the green alga Scenedesmus obliquus into the Chlamydomonas chloroplast tscA gene. This construct allows a functional analysis of conserved intron sequences in vivo, since intron rI1 is correctly spliced in chloroplasts. Using site-directed mutagenesis, deletions of the conserved intron domains V and VI were performed. In another set of experiments, each possible substitution of the strictly conserved first intron nucleotide G1 was generated, as well as each possible single and double mutation of the tertiary base pairing gamma-gamma ' involved in the formation of the intron's tertiary RNA structure. In most cases, the intron mutations showed the same effect on in vivo intron splicing efficiency as they did on the in vitro self-splicing reaction, since catalytic activity is provided by the intron RNA itself. In vivo, all mutations have additional effects on the chimeric tscA -rI1 RNA, most probably due to the role played by trans -acting factors in intron processing. Substitutions of the gamma-gamma ' base pair lead to an accumulation of excised intron RNA, since intron stability is increased. In sharp contrast to autocatalytic splicing, all point mutations result in a complete loss of exon RNA, although the spliced intron accumulates to high levels. Intron degradation and exon ligation only occur in double mutants with restored base pairing between the gamma and gamma' sites. Therefore, we conclude that intron degradation, as well as the ligation of exon-exon molecules, depends on the tertiary intron structure. Furthermore, our data suggest that intron excision proceeds in vivo independent of ligation of exon-exon molecules.  (+info)

Identification of cis-acting RNA leader elements required for chloroplast psbD gene expression in Chlamydomonas. (7/1304)

The psbD mRNA of Chlamydomonas reinhardtii is one of the most abundant chloroplast transcripts and encodes the photosystem II reaction center polypeptide D2. This RNA exists in two forms with 5' untranslated regions of 74 and 47 nucleotides. The shorter form, which is associated with polysomes, is likely to result from processing of the larger RNA. Using site-directed mutagenesis and biolistic transformation, we have identified two major RNA stability determinants within the first 12 nucleotides at the 5' end and near position -30 relative to the AUG initiation codon of psbD. Insertion of a polyguanosine tract at position -60 did not appreciably interfere with translation of psbD mRNA. The same poly(G) insertion in the nac2-26 mutant, which is known to be deficient in psbD mRNA accumulation, stabilized the psbD RNA. However, the shorter psbD RNA did not accumulate, and the other psbD RNAs were not translated. Two other elements were found to affect translation but not RNA stability. The first comprises a highly U-rich sequence (positions -20 to -15), and the second, called PRB1 (positions -14 to -11), is complementary to the 3' end of the 16S rRNA. Changing the PRB1 sequence from GGAG to AAAG had no detectable effect on psbD mRNA translation. However, changing this sequence to CCUC led to a fourfold diminished rate of D2 synthesis and accumulation. When the psbD initiation codon was changed to AUA or AUU, D2 synthesis was no longer detected, and psbD RNA accumulated to wild-type levels. The singular organization of the psbD 5' untranslated region could play an important role in the control of initiation of psbD mRNA translation.  (+info)

Direct measurement of inter-doublet elasticity in flagellar axonemes. (8/1304)

The outer doublet microtubules in ciliary and flagellar axonemes are presumed to be connected with each other by elastic links called the inter-doublet links or the nexin links, but it is not known whether there actually are such elastic links. In this study, to detect the elasticity of the putative inter-doublet links, shear force was applied to Chlamydomonas axonemes with a fine glass needle and the longitudinal elasticity was determined from the deflection of the needle. Wild-type axonemes underwent a high-frequency, nanometer-scale vibration in the presence of ATP. When longitudinal shear force was applied, the average position of the needle tip attached to the axoneme moved linearly with the force applied, yielding an estimate of spring constant of 2.0 (S.D.: 0.8) pN/nm for 1 microm of axoneme. This value did not change in the presence of vanadate, i.e., when dynein does not form strong cross bridges. In contrast, it was at least five times larger when ATP was absent, i.e., when dynein forms strong cross bridges. The measured elasticity did not significantly differ in various mutant axonemes lacking the central-pair microtubules, a subset of inner-arm dynein, outer-arm dynein, or the radial spokes, although it was somewhat smaller in the latter two mutants. It was also observed that the shear displacement in an axoneme in the presence of ATP often took place in a stepwise manner. This suggests that the inter-doublet links can reversibly detach from and reattach to the outer doublets in a cooperative manner. This study thus provides the first direct measure of the elasticity of inter-doublet links and also demonstrates its dynamic nature.  (+info)

Cell growth is tightly coupled to nutrient availability. The target of rapamycin (TOR) kinase transmits nutritional and environmental cues to the cellular growth machinery. TOR functions in two distinct multiprotein complexes, termed TOR complex 1 (TORC1) and TOR complex 2 (TORC2). While the structure and functions of TORC1 are highly conserved in all eukaryotes, including algae and plants, TORC2 core proteins seem to be missing in photosynthetic organisms. TORC1 controls cell growth by promoting anabolic processes, including protein synthesis and ribosome biogenesis, and inhibiting catabolic processes such as autophagy. Recent studies identified rapamycin-sensitive TORC1 signaling regulating cell growth, autophagy, lipid metabolism, and central metabolic pathways in the model unicellular green alga Chlamydomonas reinhardtii. The central role that microalgae play in global biomass production, together with the high biotechnological potential of these organisms in biofuel production, has drawn attention

Expression of a histidine-tagged RNA pyrophosphohydrolase in Chlamydomonas reinhardtii for localization studiesExpression of a histidine-tagged RNA pyrophosphohydrolase in Chlamydomonas reinhardtii for localization studies
RNA pyrophosphohydrolase (RppH) catalyzes the removal of pyrophosphate from 5 triphosphorylated RNAs thereby initiating RNA degradation. The enzyme has originally been identified in bacteria but homologs are present in eukaryotes where they are thought to be located in plastids or mitochondria. A homolog of the bacterial RNA pyrophosphohydrolase is present in the unicellular green alga Chlamydomonas reinhardtii suggesting that Chlamydomonas RppH has a role in mRNA degradation in the chloroplast of the alga. The purpose of this project was to determine the localization of the RppH homologue in C. reinhardtii. Localization was investigated using two different constructs, a histidine-tagged version of the Chlamydomonas rppH and a histidine-tagged 5rppH-GFP construct.. A plasmid vector containing Chlamydomonas rppH-6xHN was introduced into C. reinhardtii by nuclear transformation. PCR, RT-PCR, sequencing, and DNA and RNA blotting techniques were used to indentify positive transformants at the DNA ...

The green alga Chlamydomonas reinhardtii is a key model organism for studying photosynthesis and oxidative stress in unicellular eukaryotes. Using a forward genetics approach, we have identified and characterized a mutant x32, which lacks a predicted protein named CGLD1 (Conserved in Green Lineage and Diatom 1) in GreenCut2, under normal and stress conditions. We show that loss of CGLD1 resulted in minimal photoautotrophic growth and PSII activity in the organism. We observed reduced amount of PSII complex and core subunits in the x32 mutant based on blue-native (BN)/PAGE and immunoblot analysis. Moreover, x32 exhibited increased sensitivity to high-light stress and altered tolerance to different reactive oxygenic species (ROS) stress treatments, i.e. decreased resistance to H2O2/or tert-Butyl hydroperoxide (t-BOOH) and increased tolerance to neutral red (NR) and rose bengal (RB) that induce the formation of singlet oxygen, respectively.

3′-Processed mRNA Is Preferentially Translated in Chlamydomonas reinhardtii Chloroplasts | Molecular and Cellular Biology3′-Processed mRNA Is Preferentially Translated in Chlamydomonas reinhardtii Chloroplasts | Molecular and Cellular Biology
The data presented here suggest that 3′ end processing may be required for translation of atpB and rbcLmRNAs in Chlamydomonas chloroplasts. Unprocessed atpB transcripts, defined as those that do not accumulate as an abundant size class of approximately 2 kb, were only present in nonpolysomal fractions. Processed mRNAs were present in both polysomal and nonpolysomal fractions. Since the 3′ ends of most chloroplast transcripts are generated from longer pre-mRNAs by exo- and/or endonucleolytic mechanisms (17, 36, 37, 44, 47), this 3′ processing apparatus may interact with or signal the translational machinery.. Our ability to detect a heterogeneous collection of putative processing intermediates or incorrectly processed transcripts for atpBand rbcL suggests that these molecules are relatively stable in the chloroplast. When they were analyzed by RNase protection, it was possible to detect partially processed transcripts in theChlamydomonas chloroplast petD-trnR region (29), and in certain ...

Investigations of Chlamydomonas reinhardtii ergosterol biosynthesis by Kristy Marie BrumfieldInvestigations of Chlamydomonas reinhardtii ergosterol biosynthesis by Kristy Marie Brumfield
Ergosterol is the major sterol found in the membranes of Chlamydomonas reinhardtii. While past studies have identified some ergosterol mutants in C. reinhardtii, very little is known about sterol biosynthesis pathways in this species. With the elucidation of the Chlamydomonas genome, bioinformatics analysis has allowed us to determine potential genes involved in ergosterol biosynthesis. With this knowledge, a working model of the pathway was designed for future analysis. Several of the ergosterol biosynthetic genes were analyzed in respect to their role and involvement in flagellar regeneration. These genes were upregulated during the regrowth of the flagella. Also Chlamydomonas strains lacking flagella were analyzed by Q-RT PCR to determine what role ergosterol biosynthetic genes played in the absence of their flagella. Finally, one of the genes with homology to the yeast sterol C-5 desaturase, ERG3, was chosen for further analysis. To test whether ERG3 of C. reinhardtii had a similar function, yeast

Flagellar Synchronization Is a Simple Alternative to Cell Cycle Synchronization for Ciliary and Flagellar StudiesFlagellar Synchronization Is a Simple Alternative to Cell Cycle Synchronization for Ciliary and Flagellar Studies
The unicellular green alga Chlamydomonas reinhardtii is an ideal model organism for studies of ciliary function and assembly. In assays for biological and biochemical effects of various factors on flagellar structure and function, synchronous culture is advantageous for minimizing variability. Here, we have characterized a method in which 100% synchronization is achieved with respect to flagellar length but not with respect to the cell cycle. The method requires inducing flagellar regeneration by amputation of the entire cell population and limiting regeneration time. This results in a maximally homogeneous distribution of flagellar lengths at 3 h postamputation. We found that time-limiting new protein synthesis during flagellar synchronization limits variability in the unassembled pool of limiting flagellar protein and variability in flagellar length without affecting the range of cell volumes. We also found that long- and short-flagella mutants that regenerate normally require longer and ...

The unicellular green alga Chlamydomonas reinhardtii excels at acclimating to a changing environment. We analyzed expression patterns of its three genomes in cells grown under light-dark cycles. Nearly 85% of transcribed genes show differential expression, with different sets of transcripts being up-regulated over the course of the day to coordinate cellular growth before undergoing cell division. Parallel measurements of select metabolites and pigments, physiological parameters and a subset of proteins allow us to infer metabolic events and to evaluate the impact of the transcriptome on the proteome. Among new findings is the observation that Chlamydomonas exhibits low respiratory activity at night and relies instead on fermentative metabolism; we propose that the ferredoxin FDX9 acts as the electron donor to fermentative hydrogenases. The light stress responsive genes PSBS, LHCSR1 and LHCSR3 all show an acute response to light at dawn under abrupt dark-to light transitions. LHCSR3 genes also ...

Adenosine 3:5-Cyclic Monophosphate in Chlamydomonas reinhardtii: Isolation and Characterization. | Semantic ScholarAdenosine 3:5-Cyclic Monophosphate in Chlamydomonas reinhardtii: Isolation and Characterization. | Semantic Scholar
Chlamydomonas reinhardtii contains a factor that can replace adenosine 3:5-cyclic monophosphate (cAMP) in the stimulation of rabbit-muscle protein kinase. The factor cochromatographs and coelectrophoreses with authentic cAMP, and is inactivated by beef heart cyclic nucleotide phosphodiesterase. When C. reinhardtii is exposed to aminophylline (theophylline(2) ethylenediamine), the concentration of the factor in the cells increases within 1 hr, from about 25 pmol of cAMP equivalents per g dry weight to more than 250 pmol. Cyclic nucleotide phosphodiesterase activity is present in crude extract of C. reinhardtii and is inhibited by theophylline. We conclude that cAMP occurs in C. reinhardtii and that the endogenous concentration is governed at least in part by a theophylline-sensitive cyclic nucleotide phosphodiesterase. These findings provide a sound basis for attributing the effects of methylxanthines on flagellar function and regeneration in C. reinhardtii to the resultant elevation of endogenous cAMP

The green alga Chlamydomonas reinhardtii possesses a CO2 concentratingmechanism (CCM) which helps in successful acclimationto low CO2 conditions. Current models of the CCM postulate that aseries of ion transporters bring HCO3- from outside the cell to thethylakoid lumen, where the carbonic anhydrase CAH3 dehydratesaccumulated HCO3- to CO2, raising the CO2 concentration forRubisco. Previously, HCO3- transporters have been identified atboth the plasma membrane and the chloroplast envelope, butthe transporter thought to be on the thylakoid membrane hasnot been identified. Three paralogous genes (BST1, BST2, BST3)belonging to the bestrophin family have been found to be upregulatedin low CO2 conditions, and their expression is controlledby CIA5, a transcription factor that controls many CCM genes.YFP fusions demonstrate that all three proteins are located onthe thylakoid membrane, and interactome studies indicate thatthey might associate with chloroplast CCM components.

The nuclear genome of the model organism Chlamydomonas reinhardtii contains genes for a dozen hemoglobins of the truncated lineage. Of those, THB1 is known to be expressed, but the product and its function have not yet been characterized. We present mutagenesis, optical, and nuclear magnetic resonance data for the recombinant protein and show that at pH near neutral in the absence of added ligand, THB1 coordinates the heme iron with the canonical proximal histidine and a distal lysine. In the cyanomet state, THB1 is structurally similar to other known truncated hemoglobins, particularly the heme domain of Chlamydomonas eugametos LI637, a light-induced chloroplastic hemoglobin. Recombinant THB1 is capable of binding nitric oxide (NO(*)) in either the ferric or ferrous state and has efficient NO(*) dioxygenase activity.

The Involvement of a Multicopper Oxidase in Iron Uptake by the Green Algae Chlamydomonas reinhardtii | Plant PhysiologyThe Involvement of a Multicopper Oxidase in Iron Uptake by the Green Algae Chlamydomonas reinhardtii | Plant Physiology
In this report, we present novel evidence linking FLP to high-affinity Fe transport and propose that FLP is a ferroxidase, functioning in the reoxidation of Fe2+ before its uptake into the cell. Initial evidence in support of this hypothesis comes from the deduced FLP amino acid sequence. FLP contains two multicopper oxidase I and one multicopper oxidase signature II motifs. In addition, the amino acid sequence of FLP shows the highest homology to multicopper oxidases in mammals (HEPH and ceruloplasmin) and yeast (FET3). These proteins are ferroxidases that are themselves involved in high-affinity Fe assimilation (Stearman et al., 1996;Askwith and Kaplan, 1998; Mukhopadhyay et al., 1998; Attieh et al., 1999; Vulpe et al., 1999). The involvement of FLP in Fe homeostasis is evident from the regulation of its synthesis. Both the transcription of the FLP gene and synthesis of FLP are greatly increased in Fe-deficient cells and reversed after resupply of Fe. Although we have not demonstrated the ...

TY - JOUR. T1 - Translational regulation of light-harvesting complex expression during photoacclimation to high-light in Chlamydomonas reinhardtii. AU - McKim, S M. AU - Durnford, D G. PY - 2006/11/14. Y1 - 2006/11/14. N2 - When challenged with excess light, the green alga Chlamydomonas reinhardtii responds, in part, by down-regulating light harvesting capacity at Photosystem II while concomitantly reorganising cellular metabolism to increase sink capacity. We examined the role of translational control during different stages of photoacclimation by analysing polysome profiles of two different light-harvesting complex (LHC) genes encoding a major LHCII component (Lhcbm) and CP29 (Lhcb4) plus iron superoxide dismutase (FeSOD), and through measurement of protein synthesis by in vivo labelling. Within two hours following transfer of low-light (LL) acclimated cultures into high-light (HL), Lhcbm transcripts are off-loaded from polysomes indicating a decline in translational initiation. Lhcbm ...

We present a new Chlamydomonas reinhardtii flagellar mutant in which central pair projections are missing and the central pair microtubules are twisted along the length of the flagellum. We have named this mutant tcp1 for twisted central pair. Immunoblots using an antibody that recognizes the heavy chain of sea urchin kinesin reveal that a 70 kDa protein present in wild-type and pf18 (central pairless) axonemes is absent in tcp1, suggesting the presence of an uncharacterized kinesin associated with the central pair apparatus. We demonstrate that the kinesin-like protein Klp1 is not attached to central pair microtubules in tcp1, but rather is located in, or is part of, a region we have termed the internal axonemal matrix. It is proposed that this matrix acts as a scaffold for axonemal proteins that may also be associated with the central pair apparatus.. ...

Fusion of green fluorescent protein (GFP) to proteins is a powerful method to investigate dynamic processes in vivo. The green flagellate Chlamydomonas reinhardtii is a model organism for studying the eukaryotic flagella. In this work the GFP-tagging of proteins was employed in order to analyse proteins of the flagellar basal apparatus. Striated fiber assembling (SFA), centrin and deflagellation induced protein of 13 kDa (DIP13) were tagged with GFP at the C-terminal domain. In addition SFA was tagged at the N-terminal domain. The chimeric genes were stably transformed in C. reinhardtii. SFA is the mayor component of the striated microtubule associated fibers (SMAFS). GFP tagged SFA was incorporated into this fibers. N-terminal tagged SFA had similar properties like the wild-type protein. The length of the fibers increased with the strength of expression. The head domain of SFA is essential for fiber formation and photobleaching experiments did not show a pronounced dynamic of the fibers. The ...

Carbonic Anhydrase and Carbonic Anhydrase like Genes of Chlamydomonas Reinhardtii - OpenThesisCarbonic Anhydrase and Carbonic Anhydrase like Genes of Chlamydomonas Reinhardtii - OpenThesis
Carbonic anhydrase (CA) is a zinc containing metalloenzyme that catalyzes the reversible interconversion of CO2 and HCO3-. There are three evolutionarily unrelated CA families designated alpha, beta and gamma CA. Vertebrates have members of the alpha CA family, while higher plants, algae and cyanobacteria have members belonging to all three CA families. In the green alga, Chlamydomonas reinhardtii, five CAs have previously been identified including three alpha CAs and two beta CAs. This dissertation describes the identification and characterization of new CA genes from C. reinhardtii. Four new CA or CA like genes have been discovered including two beta CAs and two gamma CAs. Three CAs were investigated further including the alpha CA Cah3, one of the new beta CAs, Cah6; and a new gamma CA designated Gclp1 for gamma CA like protein. Cah3 is an alpha CA located in the thylakoid. Past studies with two Cah3 mutants, ca-1 and cia3 have shown that Cah3 plays an important role in the CO2 concentrating ...

en] Photosynthetic activities were analyzed in Chlamydomonas reinhardtii mitochondrial mutants affected in different complexes (I, III, IV, I + III, and I + IV) of the respiratory chain. Oxygen evolution curves showed a positive relationship between the apparent yield of photosynthetic linear electron transport and the number of active proton-pumping sites in mitochondria. Although no significant alterations of the quantitative relationships between major photosynthetic complexes were found in the mutants, 77 K fluorescence spectra showed a preferential excitation of photosystem I (PSI) compared with wild type, which was indicative of a shift toward state 2. This effect was correlated with high levels of phosphorylation of light-harvesting complex II polypeptides, indicating the preferential association of light-harvesting complex II with PSI. The transition to state 1 occurred in untreated wild-type cells exposed to PSI light or in 3-(3,4-dichlorophenyl)-1,1-dimethylurea-treated cells exposed ...

Monoclonal and polyclonal antibodies raised against algal centrin, a protein of algal striated flagellar roots, were used to characterize the occurrence and distribution of this protein in interphase and mitotic Chlamydomonas cells. Chlamydomonas centrin, as identified by Western immunoblot procedures, is a low molecular (20,000-Mr) acidic protein. Immunofluorescence and immunogold labeling demonstrates that centrin is a component of the distal fiber. In addition, centrin-based flagellar roots link the flagellar apparatus to the nucleus. Two major descending fibers extend from the basal bodies toward the nucleus; each descending fiber branches several times giving rise to 8-16 fimbria which surround and embrace the nucleus. Immunogold labeling indicates that these fimbria are juxtaposed to the outer nuclear envelope. Earlier studies have demonstrated that the centrin-based linkage between the flagellar apparatus and the nucleus is contractile, both in vitro and in living Chlamydomonas cells ...

To make the CrPKD2-GFP fusion, the C. reinhardtii bacterial artificial chromosome clone 18K16 (https://www.genome.clemson.edu/cgi-bin/orders) was cut with EcoRV and SpeI, generating an ∼18-kb fragment, which included the entire CrPKD2 gene and its promoter. This fragment was subcloned into the EcoRV and SpeI sites of pBluescript II KS+ (Stratagene), generating a plasmid named pHK25. This plasmid was cut with HindIII, generating three fragments. One of these fragments, an 8-kb fragment containing the promoter and most of the genomic DNA encoding CrPKD2, was cloned into the HindIII site of the pBluescript KS+, generating pHK28. A second fragment, a 5.8-kb fragment containing the last two introns, exons, the 3′ UTR of CrPKD2, and the KS+ vector, was religated to produce pHK26.. To tag the CrPKD2 gene, we cloned the GFP gene into a unique EcoRI site in intron 11, flanked by the first intron of RBCS2 (Goldschmidt-Clermont and Rahire, 1986). For this, the two ends of the intron were subcloned as ...

MicroRNAs play an important role in abiotic stress responses in higher plants and animals, but their role in stress adaptation in algae remains unknown. In this study, the expression of identified and putative miRNAs in Chlamydomonas reinhardtii was assessed using quantitative polymerase chain reaction; some of the miRNAs (Cre-miR906-3p) were up-regulated, whereas others (Cre-miR910) were downregulated when the species was subjected to multiple abiotic stresses. With degradome sequencing data, we also identified ATP4 (the d-subunit of ATP synthase) and NCR2 (NADPH: cytochrome P450 reductase) as one of the several targets of Cre-miR906-3p and Cre-miR910, respectively. Q-PCR data indicated that ATP4, which was expressed inversely in relation to Cre-miR906-3p under stress conditions. Overexpressing of Cre-miR906-3p enhanced resistance to multiple stresses; conversely, overexpressing of ATP4 produced the opposite effect. These data of Q-PCR, degradome sequencing and adaptation of overexpressing ...

S.P. Mayfield, P. Lee, P. Pettersson, J. Marìn-Navarro, A. Manuell, M. Muto, M. Tran We have developed a system for expressing recombinant proteins, including human therapeutic proteins, in the chloroplast of the eukaryotic green alga Chlamydomonas reinhardtii. Expression of therapeutic proteins in eukaryotic algae offers several advantages over more traditional protein expression systems. Algae are efficient at producing complex mammalian proteins, stable transgenic lines can be generated in a few weeks, and algal systems can be scaled to high levels for a fraction of the cost of traditional fermentation systems.. We have expressed several recombinant proteins in algae, including human monoclonal antibodies. Antibodies are complex multiprotein molecules that are difficult to express in simple expression systems and expensive to produce in mammalian cell culture. We have had good success in producing these complex proteins in algal chloroplasts. We have also expressed eukaryotic protein toxins, ...

Beyond Complementation. Map-Based Cloning in Chlamydomonas reinhardtii | Plant PhysiologyBeyond Complementation. Map-Based Cloning in Chlamydomonas reinhardtii | Plant Physiology
Our initial mapping data placed Mcd4 into two possible locations. In both cases, it was desirable to generate bacterial artificial chromosome (BAC) contigs for eventual complementation, as well as additional markers. As a case study, we describe how BAC contigs can be extended using Chlamydomonas resources and our experience in generating site-specific markers.. Several BAC libraries have been constructed for Chlamydomonas, two of which are available through the Clemson Genomics Institute (http://www.genome.clemson.edu/groups/bac/). In addition, BAC contigs (http://www.biology.duke.edu/chlamy_genome/BAC/index.html) have been assembled for most of the STS and RFLP markers. In the case of mcd4, Gsp1 resides on scaffold 2 and CNA45 on scaffold 66. A 41-BAC contig exists for scaffold 2 covering approximately 1,000 kb (R. Nguyen, personal communication), and a smaller contig is linked to scaffold 66 and CNA45 (Fig. 6). An unknown amount of DNA separates scaffolds 2 and 66; such discontinuities in the ...

Centrin, a 20-kD phosphoprotein with four calcium-binding EF-hands, is present in the centrosome/basal body apparatus of the green alga Chlamydomonas reinhardtii in three distinct locations: the nucleus-basal body connectors, the distal striated fibers, and the flagellar transition regions. In each location, centrin is found in fibrous structures that display calcium-mediated contraction. The mutant vfl2 has structural defects at all of these locations and is defective for basal body localization and/or segregation. We show that the vfl2 mutation is a G-to-A transition in the centrin structural gene which converts a glutamic acid to a lysine at position 101, the first amino acid of the E-helix of the proteins third EF-hand. This proves that centrin is required to construct the nucleus-basal body connectors, the distal striated fibers, and the flagellar transition regions, and it demonstrates the importance of amino acid 101 to normal centrin function. Based on immunofluorescence analysis using ...

While conducting a screen for genes affecting pyrenoid function in the green alga Chlamydomonas reinhardtii, graduate student and the studys first author Alan Itakura and postdoctoral researcher Leif Pallesen, both in the Jonikas group, uncovered a gene called SAGA1 (Starch Granules Abnormal-1), the loss of which causes cells to grow poorly. When the researchers, including the studys co-first author, Kher Xing (Cindy) Chan in Howard Griffiths group at the University of Cambridge, examined the mutant cells, they noticed that SAGA1 mutants possess multiple pyrenoids-up to 10 per cell. This was surprising since normal cells almost always contain just one pyrenoid. Intrigued, the team decided to investigate further.. Because the SAGA1 protein is predicted to contain a starch-binding domain, the researchers first explored whether loss of the SAGA1 gene affects the architecture of the starch plates that make up the pyrenoid sheath. Indeed, the pyrenoids in SAGA1-deficient cells have fewer and ...

High light (HL) stress adversely affects growth, productivity and viability of photosynthetic organisms. The green alga Chlamydomonas reinhardtii is a model system to study photosynthesis and light stress. Comparative proteomics of wild-type and two very high light (VHL)-resistant mutants, VHLR-S4 and VHLR-S9, revealed complex alterations in response to excess light. A twodimensional reference map of the soluble subproteome was constructed representing about 1500 proteins. A total of 83 proteins from various metabolic pathways were identified by peptide mass fingerprinting. Quantitative comparisons of 444 proteins showed 105 significantly changed proteins between wild type and mutants under different light conditions. Commonly, more proteins were decreased than increased, but different proteins were affected in each genotype. Proteins uniquely altered in either VHLR mutant may be involved in VHL resistance. Such candidate proteins similarly altered without light stress, thus possibly ...

The goal of our scientific work is the molecular analysis of the biogenesis of photosynthetic thylakoid membranes which represent one of the most complex energy-transducing membranes currently known. We especially ask the questions how the biogenesis process is organized in space, what the molecular working mode of assisting factors is and how these factors developed by evolutionary means.. A second aspect of our work concerns the transformation of a cyanobacterium into an organelle of the plant cell, namely the chloroplast. This domestification of a former free-living procaryote throughout evolution was enabled by the advention of an intracellular communication system harmonizing gene expression in the former cyanobacterium and its host. This system is based on regulatory RNA/protein compexes which we study by applying genetic and biochemical techniques in the unicellular model green alga Chlamydomonas reinhardtii.. ...

Nitrite plays an important role in the nitrogen metabolism of most cells, including Chlamydomonas reinhardtii. We have shown that vegetative cells of C. reinhardtii are attracted by nitrite. The Nia1nit2 mutant with defects in genes encoding the nitrate reductase and regulatory protein NIT2 respectively was found to exhibit normal chemotaxis to nitrite. The data suggest that chemotaxis events appear to be specific and independent of those involved in nitrate assimilation. Unlike vegetative cells and noncompetent pregametes, mature gametes did not show chemotaxis to nitrite. Just like gamete formation, the change in chemotaxis mode is controlled by the sequential action of two environmental cues, removal of nitrogen from the medium and light. Comparative analysis of wild-type and RNAi strains with reduced level of phototropin has indicated that switch-off of chemotaxis towards nitrite is dependent on phototropin. The studies revealed individual elements of the phototropin-dependent signal transduction

Gametogenesis in the Chlamydomonas reinhardtii minus Mating Type Is Controlled by Two Genes, MID and MTD1 | GeneticsGametogenesis in the Chlamydomonas reinhardtii minus Mating Type Is Controlled by Two Genes, MID and MTD1 | Genetics
This model does not account for two published observations: An mt+ strain carrying the MID gene transposed to an autosome differentiates as minus, as do mt+ cells transformed with the MID gene, even though neither possesses a copy of the MTD1 gene (Ferris and Goodenough 1997). To reconcile these observations with the results reported here, we are led to propose that plus gametes express a system, the MTD1-equivalent system, that is functionally equivalent to the MTD1 system but achieves this outcome without requiring the Mtd1 protein itself. When MID is introduced into a plus background, the MTD1-equivalent system enables sufficiently high MID expression to allow transformants to undergo minus differentiation, albeit success is usually incomplete (see results and Ferris and Goodenough 1997), meaning that the MTD1-equivalent system is not repressible by Mid. Importantly, at least one essential gene in the posited plus MTD-equivalent system must be resident in the MT+ locus. If the system were ...

Induction and regulation of expression of a low-CO2-induced mitochondrial carbonic anhydrase in Chlamydomonas reinhardtiiInduction and regulation of expression of a low-CO2-induced mitochondrial carbonic anhydrase in Chlamydomonas reinhardtii
The time course of and the influence of light intensity and light quality on the induction of a mitochondrial carbonic anhydrase (CA) in the unicellular green alga Chlamydomonas reinhardtii was characterized using western and northern blots. This CA was expressed only under low-CO2 conditions (ambient air). In asynchronously grown cells, the mRNA was detected 15 min after transfer from air containing 5% CO2 to ambient air, and the 21-kD polypeptide was detected on western blots after 1 h. When transferred back to air containing 5% CO2, the mRNA disappeared within 1 h and the polypeptide was degraded within 3 d. Photosynthesis was required for the induction in asynchronous cultures. The induction increased with light up to 500 mu mol m(-2) s(-1), where saturation occurred. In cells grown synchronously, however, expression of the mitochondrial CA was also detected in darkness. Under such conditions the expression followed a circadian rhythm, with mRNA appearing in the dark 30 min before the light ...

Robust Transgene Expression from Bicistronic mRNA in the Green Alga Chlamydomonas reinhardtii | G3: Genes | Genomes | GeneticsRobust Transgene Expression from Bicistronic mRNA in the Green Alga Chlamydomonas reinhardtii | G3: Genes | Genomes | Genetics
When Venus was used as a GOI with this system, a positive correlation was found between paromomycin resistance and Venus fluorescence, indicating that expression from the two ORFs is coupled. It initially seemed possible that a mechanism such as stop-codon read through (Jackson et al. 2012) might result in expression of the GOI and APHVIII products as a single fusion protein that provides paromomycin resistance. However, this appears not to be the case, because the method works equally well when two or three different stop codons are inserted between the ORFs, and/or the ORFs are placed out-of-frame, and Western blotting detected no such fusion products. Thus, it seems most likely that APHVIII is translated by post-termination reinitiation (Kozak 2007; Skabkin et al. 2013), in which the ribosome remains associated with the mRNA after termination, continues scanning, and reinitiates translation at a downstream (or, occasionally, upstream: Skabkin et al. 2013) AUG. Such events have been well ...

Mother puts organelles in their place | JCBMother puts organelles in their place | JCB
Like a strict parent, the mother centriole keeps order in the cell by telling other organelles where to sit, according to new work by Jessica Feldman, Wallace Marshall (University of California, San Francisco, CA), and Stefan Geimer (Universität Bayreuth, Bayreuth, Germany).. Marshalls team is interested in what controls the intracellular geometry of organelle positioning. To address this topic, they focus on one organelle that is well-known for its specific positioning: the centriole.. The tethered pair of mother and daughter centrioles is the major component of the centrosome complex and also promotes the assembly of cilia. Thus cilia can act as a cell surface indicator of centriole positioning. The team used the unicellular alga Chlamydomonas reinhardtii, which normally has two cilia at its apex, to scan for mutants in which cilia were misplaced.. In certain misplaced cilia mutants, the fibers that normally tether mother and daughter centrioles were absent. The team found that whereas the ...

C2cd3 is required for cilia formation and Hedgehog signaling in mouse | DevelopmentC2cd3 is required for cilia formation and Hedgehog signaling in mouse | Development
Cilia and flagella are cell surface organelles with microtubule-based axonemal cores. Although these organelles have been known to biologists for centuries, only in the last five years has it been recognized that cilia are crucial for mammalian embryonic development as well as for the function of multiple adult organs (Pan et al., 2005). Many potential ciliary proteins have been identified in various species in recent years using biochemical, comparative genomic and proteomic methods. Nevertheless, the spectrum of factors required for the formation and/or function of cilia, as well as the molecular mechanisms underlying the regulation of cilia biogenesis, have yet to be fully revealed.. Two multiprotein complexes, the intraflagellar transport (IFT, complex A and B) complexes, are present in the green alga Chlamydomonas reinhardtii (Rosenbaum and Witman, 2002). The IFT complexes move within the flagella, suggesting that they are likely to be involved in the transportation of molecules inside the ...

Photosynthetic microalgae hold promise as green cell factories for sustainable light-driven bio-production processes. These organisms can be cultivated with freely available sunlight energy and CO2 as a sole carbon source, making them ideal chassis for sustainable production processes. Microalgae are already natural sources of many interesting bio-products including carotenoids, lipids, and polysaccharides. However, expanding the range as well as value of the compounds produced by microalgae through genetic engineering can increase the economic competitiveness of light-driven algal production platforms. In comparison to bacteria or yeasts, genetic engineering of eukaryotic microalgae has lagged significantly behind due to characteristically low transgene expression levels. Work in our research group has focused on engineering increased and reliable levels of nuclear transgene expression in the fast growing, Chlorophyceaen microalga Chlamydomonas reinhardtii, with the aim of generating ...

Biohydrogen - WikipediaBiohydrogen - Wikipedia
In 1933, Marjory Stephenson and her student Stickland reported that cell suspensions catalysed the reduction of methylene blue with H2. Six years later, Hans Gaffron observed that the green photosynthetic alga Chlamydomonas reinhardtii, would sometimes produce hydrogen.[17] In the late 1990s Anastasios Melis discovered that deprivation of sulfur induces the alga to switch from the production of oxygen (normal photosynthesis) to the production of hydrogen. He found that the enzyme responsible for this reaction is hydrogenase, but that the hydrogenase lost this function in the presence of oxygen. Melis also discovered that depleting the amount of sulfur available to the algae interrupted their internal oxygen flow, allowing the hydrogenase an environment in which it can react, causing the algae to produce hydrogen.[18] Chlamydomonas moewusii is also a promising strain for the production of hydrogen.[19][20] ...

Origin of Polar Order in Dense Suspensions of Phototactic Micro-SwimmersOrigin of Polar Order in Dense Suspensions of Phototactic Micro-Swimmers
A main question for the study of collective motion in living organisms is the origin of orientational polar order, i.e., how organisms align and what are the benefits of such collective behaviour. In the case of micro-organisms swimming at a low Reynolds number, steric repulsion and long-range hydrodynamic interactions are not sufficient to explain a homogeneous polar order state in which the direction of motion is aligned. An external symmetry-breaking guiding field such as a mechanism of taxis appears necessary to understand this phonemonon. We have investigated the onset of polar order in the velocity field induced by phototaxis in a suspension of a motile micro-organism, the algae Chlamydomonas reinhardtii, for density values above the limit provided by the hydrodynamic approximation of a force dipole model. We show that polar order originates from a combination of both the external guiding field intensity and the population density. In particular, we show evidence for a linear dependence of a

The focus of our groups activities is the analysis and manipulation of metabolic pathways. With an increased understanding of the regulation of metabolism, scientists and engineers can rationally manipulate pathways to produce novel compounds or increase the production of specialty compounds. Quantifying metabolic flux is a critical technology that forms the basis for rational metabolic engineering. Our group has been developing the mathematical modeling and experimental tools for the particularly difficult problem of quantifying fluxes in photoautotrophic organisms. The current focus is on quantifying intracellular metabolite fluxes in cyanobacteria, algae and plants by liquid chromatography-mass spectrometry (LC-MS/MS) and gas chromatography-MS (GC/MS). We have also constructed a genome scale metabolic model of the algae Chlamydomonas reinhardtii and performed flux balance analysis on the network, which we are comparing against experimentally determined metabolic fluxes derived from transient ...

Phylogenetic and molecular analysis of hydrogen-producing green algae - UQ eSpacePhylogenetic and molecular analysis of hydrogen-producing green algae - UQ eSpace
A select set of microalgae are reported to be able to catalyse photobiological H(2) production from water. Based on the model organism Chlamydomonas reinhardtii, a method was developed for the screening of naturally occurring H(2)-producing microalgae. By purging algal cultures with N(2) in the dark and subsequent illumination, it is possible to rapidly induce photobiological H(2) evolution. Using NMR spectroscopy for metabolic profiling in C. reinhardtii, acetate, formate, and ethanol were found to be key compounds contributing to metabolic variance during the assay. This procedure can be used to test algal species existing as axenic or mixed cultures for their ability to produce H(2). Using this system, five algal isolates capable of H(2) production were identified in various aquatic systems. A phylogenetic tree was constructed using ribosomal sequence data of green unicellular algae to determine if there were taxonomic patterns of H(2) production. H(2)-producing algal species were seen to be ...

Engineered tissues are highly limited by poor vascularization in vivo, leading to hypoxia. In order to overcome this challenge, we propose the use of photosynthetic biomaterials to provide oxygen. Since photosynthesis is the original source of oxygen for living organisms, we suggest that this could be a novel approach to provide a constant source of oxygen supply independently of blood perfusion. In this study we demonstrate that bioartificial scaffolds can be loaded with a solution containing the photosynthetic microalgae Chlamydomonas reinhardtii, showing high biocompatibility and photosynthetic activity in vitro. Furthermore, when photosynthetic biomaterials were engrafted in a mouse full skin defect, we observed that the presence of the microalgae did not trigger a native immune response in the host. Moreover, the analyses showed that the algae survived for at least 5days in vivo, generating chimeric tissues comprised of algae and murine cells. The results of this study represent a crucial ...

In the GAPDH-CP12-PRK complex, T. elongatus PRK is dimeric, as in solution (SI Appendix, Fig. S5E), and like other plant-type PRKs (6, 7). PRK has an alpha-beta-alpha sandwich fold where the central 9-strand beta-sheet is continuous across the dimer interface (Fig. 3C). The active site cleft lies between 3 loops (residues 137-164, 43-63, and 87-98). The N-terminal helical bundle of CP12 plugs this cleft and sterically blocks the active site (Fig. 3D). The charged patch created by the CP12 motif binds to complementary positively charged regions in the PRK active site (Fig. 3E), which have also been proposed to be important for negatively charged sugar phosphate substrate binding (6). Variants in the CP12 of Chlamydomonas reinhardtii, equivalent to Trp33, Glu37, and Glu38 in the conserved CP12 motif resulted in loss of complex formation (24). The conserved CP12-Trp33 is on the surface and packs against PRK, contradicting a prediction that it is buried (29). CP12-Glu33 makes a salt bridge with ...

Introduction Bio 2010 01/31/2014 The objectives of this lab were to understand natural selection and understand the biotic and abiotic characteristics of a niche. In order to understand natural selection in this lab we observed characteristics of three different algae families; Volvox, Chlamydomonas, and Gonium. By observing these algae will give us a better understanding of how a simple cellular organism evolved due to natural selection and are able to survive today. These organisms will give us context into natural selection occurring on bigger organisms as we move on in lab. Similarly, in order to understand biotic and abiotic characteristics of a niche, we observed a transect. By observing a transect will provide insight into how the biosphere works by focussing on biotic and biotic components of a home to many organisms. Procedure 1: The Volvicine Line In this experiment we observed an isogamous, single celled, motile alga called chlamydomonas. We prepared a slide of a living Chlamydomonas ...
